Be known that l, FRED S. CARR, a citizen of the United States, residing at Broekline, in e'he county of Ilorlolk and Stale oi' Massachusetts, have invented new and useful linprov-einei'ies in 'lurn-Button 'Fasteners, of which {he following is a specification.

This invention relates to a fastener loreerriage curtains and ihe like comprising a shank adapted to he attached to a. rigid support-such as the body of a vehicle or the member of frame of a vehicle top, or

lo afiexible support such a. sheet forming a para; of a top or cover, and formed to enter a hu'htonhole or eyelet in a curtain or cover portioi'i and an oblong button pivoted to the Shani; and formed to register with and freely enter :1 buttenhole when turned to one posiiion, and to he turned crosswise the bnttonhole to overhang portions of hhe "margin thereof and confine the curtain or cover pert-ion against removal from the shank. The shank is usually of oblong form corresponding to that of the huttonhole and of this character, lnown iasleners, are provided with it s... 10f yieloingy eonnaing die button n registration with the shank, ,or '0 that the button will reton Iastener in Whirh the shank and its attaching are made in a, single sheet metal pieee or part; end are adapted to cooperate in yieldingly confining the button in either of the described nosirions without the emplo'yzneni", of retaining devices supplemental 1d formed separately thcreolan view elf the fastener show- Specifica'tlon of Iietcers Faisal.

Mg. 0 is a VlGVv similar L rig. (i, snowing a modification.

9 is a fragmentary perspective view. showing another modification.

The same reference charaeiers indicale the same parts in all the figures.

The hollow shank l2 and l'he altaching base 13 of my improved fastener are made from a single blank oi? shecl melal, rouverted by a series oi operations iulo the form shown by the drawings, the base heingi; continuous and sun-ohm}.ing the inner end of the shank. The margin oi llie hase has a downwardly projeeting;- flange 'l'oruwd to hear on support. The lei) portion of lhe base may be provided with screw-ween ing;

orifices preferably hounded by tapering flanges l l. l n case the shank i not attached in a. carrying purl; by screws. the base may be provided Willi al'taehing prongs in, as indicated by .l.

The hollow shank is divided ll) slol's inlo two sections. each inrludingr practically (medial? of the wall of the shank and one half of the closed outer end or head of the shank. said head therefore including: (W0 separable head portions l2- rvhich are nor mally held yieldingly in conlaet will], or in close proximity lo each olher by the eontinuous resilient base 13.

The head portions 12 are recessed to form eoineiding jaws 16, said jar/s eolleelirely form ng lhe wall of an expansihle socaelz, adapted to receive a stud l7 projecting; downwardly from the under side of a hutton 18 the jaws lelslingly eirnltiraeing lhe sind and lacing adapted "to confine the situd and l uiiton in different positions. To give said jaws Wide hearing on the stud 1'2, 1 E preferably forniihen'i by burning; parts the head portions 12 inwardly, thus forming; lips or flanges as shown clearly h'y' 1 end "4".

l i the embodiment of the invention shown hylv 1, 6 and *1", "she said aws and stud are of angular form, the jaws irreferahl y forming an angular soeke'lz, and the section. There is, therefore, a yielding interlocking engagement between the button and shank, not only when the button is turned to position to register with the stud and enter a buttonhole therewith, but also when the button is turned so that its major axis is at right angles with the major axis of the stud, as shown by Fig. 6. When the button is turned to an intermediate position the stud l7 forces the head portions apart, as shown by Fig. 5, the jaws being permitted to close when the button and stud are turned to registering position and to the position shown by Fig. 6.

The jaws and stud may be formed to hold the button in different positions wholly by friction and without the above-described yielding interlocking engagement, as shown by Fig. 8, in which the jaws l6 are semiand the stud l7 is circular in cross Section. In this modification the diameter of the stud is preferably greater than the normal diameter of the space bounded by 'lhe jaws, so that the insertion of the stud between the jaws increases the width of the slots 15, the jaws being therefore caused to exert a constant uniform pressure on the stud.

The button and stud may be hollow and made of sheet metal as shown by Figs. 1 and 2, or may be solid as shown by Figs. Eland l. The stud is formed to project below the jaws and isupset at its inner end to engage the lower edges of the jaws, as

shown by rigs. 2 and 3, the button being thus secured to the shank. The continuous res lient base 13 constilutes an effective spring n1en1bern1aintain-' ing the shank jaws in with the button stud.

I claim I 1. A turn-button fastener conm sing a hollow sheet metal shank, a continuous sheet metal base integral with and surrounding the inner end of the shank, and adapted to be attached to a support, said shank being divided into separable sections which are connected by the base, said sections having head port-ions provided with coinciding recesses, the walls of which constitute separable jaws which are normally closed by the resilience of the base, and a button having a stud yielding-1y engaged by and adapted to rotate between said jaws.

A turn-button fastener claim 1, the said jaws being formed by flanges integral with and turned inwardly from said head portions,- and presenting relatively wide faces contacting withsaid "stud.

3. A turn-button fastener as specified by claim 1, said jaws and stud being angular to cause an interlocking engagement therebetwcen, and the stud being formed to alteryielding engagement as specified by nately separate and permit the closing of the jaws.

In testimony whereof I have ailixed my signature.
